Inventors of bicycle
In the world, there are about a billion bicycles twice as many as motorcars. Almost 400 million bicycles are in China. Every year some 50 million bicycles and 20 million cars are produced. Although Leonardo da Vinci drew some rough sketches of a contraption that looked like a bicycle, the Frenchman De Sivrac built the first bicycle-type vehicle in 1690. It was referred to as a hobbyhorse. However, it did not have pedals. Those were added in 1840 by a Scottish blacksmith, Kirkpatrick Macmillan, who is credited with inventing the real bicycle. On a penny-farthing bicycle, one pedal gave the wheel one turn. A lot of pedaling was needed to get around! With the advent of gears, bicycles could move as fast as cars. Air-filled tyres were used on bicycles before they were used on motorcars. The bicycle as we know it today – with two wheels of the same size – looks almost exactly the same as one from 1900. The first five-seat bicycle, the quindem, was built in 1940.
